effect of center pivot system lateral configuration on water application uniformity in an arid area
system evaluations were performed on 48 center pivots in different parts of saudi arabia. these systems, located on different farms in four different regions of the country, namely: riyadh, jouf, qassim and eastern regions, were evaluated to study the effect of lateral configuration on water application uniformity as regards the original vs. modified laterals. lateral configuration modification...
متن کاملInvestigation of infiltration in Center Pivot irrigation system
Use of the double ring infiltrometer to measure soil water infiltration in center pivot irrigation systems isn’t an accurate approach because the real conditions of infiltration under center pivot sprinklers is different from what happens in the double ring. In this study the infiltration parameters were evaluated in real conditions of a center pivot system. For this purpose a single ring...
متن کاملModelling evaporation and drift losses in irrigation with medium size impact sprinklers under semi-arid conditions
A proper understanding of factors affecting evaporation and drift losses in sprinkle irrigation is important for developing water conservation strategies. For estimating drift and evaporation losses during the set sprinkler irrigation event, several outdoor single-sprinkler and block irrigation tests have been conducted. Various sprinkler±nozzle±riser height combinations were used and the varia...
متن کاملThe effect of irrigation water quality on soil properties under center pivot irrigation systems in central Saudi Arabia
A field experiments were conducted for three growing seasons (2007 to 2009) at five different sites of soil types and salinity levels. Five different ground water qualities were used to irrigate five fields each with area of 50 to 54 hectares planted with wheat crop and the irrigation system used at each field was center pivot sprinkler system. The irrigated fields were located at different loc...
متن کاملPhosphorus losses in furrow irrigation runoff.
Phosphorus (P) often limits the eutrophication of streams, rivers, and lakes receiving surface runoff. We evaluated the relationships among selected soil P availability indices and runoff P fractions where manure, whey, or commercial fertilizer applications had previously established a range of soil P availabilities on a Portneuf silt loam (coarse-silty, mixed, superactive, mesic Durinodic Xeri...
